Question

The correct set of four quantum numbers for the outermost electron of k

Answer 1

Hi

the electronic configuration of potassium

1s^2 2s^2 2p^6 3s^2 3p^6 4s^1 .

now we take only outermost shell which is

4s^1

so

principal quantum(n) =4

azimuthal q.no for s(l)=0

magnetic q.no(-l to+l)=0

spin q.no=1/2

thanks for asking
